Can someone answer with steps and explanation? Thanks.

Step-by-step explanation:

Since ΔABC is mapped onto ΔDEF, we can write that:

By CPCTC:

And since ΔABC is isosceles with Vertex C:

We are given that:

Hence:

We are also given that:

The interior angles of a triangle must sum to 180°. Thus:

Substitute:

Simplify:

Isolate the equation:

Factor:

Zero Product Property:

Solve for each case:

Testing the solutions, we can see that both yields C = 112°.

Hence, our solutions are:

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
